Comparison of experimental and simulation results for the WP1 geometry. Top (a) and cross-sectional tilted views (b) of the macroporous layer. The current density was set at the constant value of 26
mA/cm2. The frame (c) shows the COMSOL-simulated cross-section. The shading represents the holes current
density; the streamlines, the hole flux streamlines.
